Skin regenerating cosmetic composition

ABSTRACT

The invention is concerned with a skin regenerating cosmetic composition which contains as active ingredient the extract of the pod and/or grain of green peas.

The invention relates to a skin regenerating cosmetic composition.

BACKGROUND OF THE INVENTION

There are many excellent compositions on the cosmetic market, the greatpart of which is based on synthetic elements. The skin regeneratingcompositions mainly due to their fat and water content improve thecondition of the skin. Recently also the use of active ingredients ofplant origin is discussed. Because of the great variety of the activeingredients of plant origin only the following are mentioned asexamples: grape, palm, fruit of the cocoa tree, gingko leaf (GermanPatent specifications Nos. 1,492,023, 1,492,118, 1,492,148, 1,617,365,1,767,098 and 2,232,733). But the plant residues obtained during theprocessing of agricultural cultivated plants and mainly waste in thepreserves industry have not been examined in view of their applicabilityin the cosmetic industry.

The aim of the present invention was to find new active ingredients ofplant origin for use in the cosmetic industry.

Another aim of the present invention was to find plant parts obtained aswaste during the processing of agricultural cultivated plants which canbe used as active ingredients in cosmetic compositions.

BRIEF DESCRIPTION OF THE INVENTION

During our experiments it has been surprisingly found that by theextraction of the pod and/or grain of green peas an active ingredient, asolution was obtained which was excellently suitable for calming theinflamed skin, improving the scarfskin formation of wounded skin, forlight protection, for treating pustules or other inflamatory formationswhen admixed in a suitable ratio with diluents and/or vehicles andoptionally other known substances used in the cosmetic industry, e.g.propolis.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to skin regenerating cosmetic compositionscomprising the extract of the pod and/or grain of green peas as activeingredient together with the usual vehicles and/or diluents.

The extract is prepared from the pod and/or grain of green peas withwater or with a mixture of water and a water miscible organic solvent,preferably with the mixture of ethanol and water by steeping or boiling.After filtering the extract the solution of the active ingredient isformulated directly or after lyophilization with the usual cosmeticvehicles and/or diluents.

The composition of the invention shows a very favorable effect.

The face lotion (Example 7) was examined on 45 women aged from 20 to 65years. The cream was applied after thorough cleaning twice a day, in themorning and evening. The treatment was continued for two weeks. Thefollowing types of face skin were examined: 35 slightly dry, 9sensitive, dry, 1 very dry skin. The cream has been absorbed well duringthe treatment, the skin became smooth, velvety. During the treatment noallergic reaction, irritative dermatitis or hypersensitivity wereobserved.

The body lotion (Example 9) was tested on 32 women aged from 17 to 68years. The composition was applied after thorough washing twice daily,in the morning and evening. The treatment was continued for two weeks.The following types of skin were examined: 2 normal sensitive, 4 drysensitive, 18 dry and 8 normal skins. The composition has been absorbedwell during each treatment, the skin became velvety, smooth, the skintightening and dryness which occurred after washing (having a bath orshower) stopped and the skin was calmed and refreshed. No allergicreaction, irritative dermatitis or hypersensitivity was observed.

The following non-limiting Examples show the compositions of theinvention and the preparation of the active ingredient.

EXAMPLE 1

Pods of green peas deprived of their grains were dried at roomtemperature in a manner usual for herbs, then crushed. 1 kg of thecrushed substance was suspended in 4.00 liters of water and steeped in adry, cool place for 24 hours. After filtration the solution was boiled,then a 20% by vol. solution was prepared with cosmetic vaseline oil. Thesolution was stored in a dry, cool, dark place until use.

EXAMPLE 2

Pods of green peas deprived of their grains were dried as in Example 1then powdered. 4.5 liters of deionized water were added to 1 kg of thepowdered substance. The mixture was boiled for 2 hours, the resultingsolution was filtered and closed hermetically until use. It was storedin a dark, cool, dry place.

EXAMPLE 3

Pods of green peas deprived of their grains were dried as in Example 1then powdered. 4.10 liters of 70% by vol. of aqueous ethanol were addedto 1 kg of the powdered substance. The substance was steeped for 72hours, then the solution was filtered and after having been covered itwas stored in a dry, cool, dark place.

EXAMPLE 4

Pods of green peas deprived of their grains were dried as in Example 1then powdered. 5 liters of deionized water were added to 1 kg of thepowdered substance. The substance was steeped for 32 hours. Afterfiltration the solution was boiled, then it was stored in a dry, cool,dark place until use.

EXAMPLE 5

Pods of green peas deprived of their grains which were obtained in thepreserves industry were crushed, then diluted with water to 4-foldvolume and steeped for 36 hours. After filtration the solution wasboiled, then stored in dry, cool, dark place.

EXAMPLE 6

1 kg of grains of green peas was ground and steeped in 5 liters ofdeionized water for 30 hours. After filtration the solution was boiled,then it was stored in dry, cool, dark place until use.

EXAMPLE 7

1 kg of grains of green peas was ground and dried as in Example 1 thenit was powdered. 4.5 liters of 70% by vol. of ethanol were added to 1 kgof the powdered substance, then the substance was steeped for 36 hours,the solution was dried and lyophilized.

EXAMPLE 8

4.0 liters of deionized water were added to 1 kg of dried and powderedgrain of green peas, the mixture was boiled for 2 hours, the solutionwas filtered and stored in a dry, cool, dark place until use.

EXAMPLE 9

The wet mixture of grains and pods of green peas obtained in thepreserves industry was dried as in Example 1 then 1 kg of the driedmixture was steeped in 4.5 liters of deionized water for 36 hours. Afterfiltration the solution was lyophilized.

EXAMPLE 10

3 kg of grain of green peas and 1 kg of pod of green peas were groundtogether then the mixture was dried as in Example 1. 1 kg of the driedmixture was boiled in 5 liters of deionized water for 3 hours. Afterfiltration the product was covered and stored in a dark, cool, dryplace.
